ONI Geyser Calculator

Geysers cycle between active and inactive states, making it difficult for players to understand the quantity of resources made available to them by the geyser. There are fan-produced Geyser Calculators that players can use to calculate the average output of a geyser given information about the geyser, and will also show how many machines or plants can be sustained by that geyser:


 * The Graphical Geyser Calculator also allows players to budget the cooling requirements to achieve a target output temperature for their geyser, e.g. cooling steam to water.
 * The ONI Calculator also calculates outputs of various buildings, plants, etc.
 * The Oxygen Not Included Database also offers a geyser calculator
